I am using Windows 2008 R2 with IIS 7.5 and have mapped the source of my website to a network drive. When I do, the below error occurs. When pointing to the local c: drive the website works.
Error Summary HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid. Detailed Error Information Module IIS Web Core Notification Unknown Handler Not yet determined Error Code 0x80070003 Config Error Cannot read configuration file Config File \\?\H:\ExcelAutomation\1.0\src\docs\web.config Requested URL http://vmwws085381.msad.ms.com:80/index.html Physical Path Logon Method Not yet determined Logon User Not yet determined Config Source -1: 0:
The solution for me was to open up IIS, click on my site, and under Advanced Settings change the physical path to the network share like
\\server\share\.. instead of using the mapped drive.
Original source that helped me arrive to this solution is here: http://forums.iis.net/t/1157959.aspx
Also, make a big mental (or written) note for yourself and other administrators: If you ever change the password for that account, do it on both servers and within the IIS connection.
For someone who is getting this error on your local system, it can happen when you share code across multiple servers or copy an existing project to a new location and it's virtual directory path still refers to an older path.
This happened to me as I was sharing a project on a Google drive and was accessing it from 2 different systems. (I know, Should've used version control system)
Right click on the project >> Web >> Create virtual directory
It will probably show a prompt. Select Yes and you are done.
The main reason behind this error is the physical path i.e web site folder cannot be under the users folder, desktop folder, or any related folder. If it's there, move it or place it on other drive and try again.
